Session Reliability keeps ICA sessions active during brief network interruptions by holding the connection open and attempting to reconnect, which can mask the true connection error. Temporarily disabling Session Reliability forces an immediate failure with a more descriptive error, allowing the administrator to identify the root cause - such as a misconfigured STA or firewall blocking the ICA port.

Authorization policies control which resources authenticated users are permitted to access, not the transport layer connection that produces this specific error.
